Title: Improvements in temperature measurements in gas turbine engines
IPC: G01J5/10
Filed: 1970-04-17
Abstract: 1292796 Measuring temperature photoelectrically GENERAL ELECTRIC CO 17 April 1970 [21 April 1969] 18502/70 Heading G1A The temperature of the combustion gas and turbine blades in a gas turbine engine is measured by using apparatus including an infrared detector focused on to the turbine blade and processing the detector output so that the maximum and minimum temperatures can be determined separately to give the respective results. In the operation of a gas turbine engine the concentration of carbon particles in the flame varies cyclically and the output of the infrared detector varies accordingly. When the concentration is minimum the detector gives a minimum output representing the temperature of the turbine blade; when maximum the blade is obscured and the gas temperature is measured. As shown silicon photo-diode 48 is mounted in housing 18 and receives infrared radiation from turbine blade 16 through lens 38 and filter 50. The interior of sight tube 34 is provided with purging holes 42 supplied with air under pressure and is also roughly turned. An output signal which varies linearly with temperature is applied at point 28 to measuring circuits 30, 32 which measure gas and blade temperatures respectively. Circuit 30 comprises a network 62 having a charging lug 70, 72 and a discharging lug 74, 76 the resistance values of which are adjustable so that capacitor 64 charges up to the peak level of the signal at 28 rapidly and then discharges slowly so that the voltage on it represents the temperature of the gas. Basically in circuit 32 the resistors of network 78 are adjusted so that capacitor 84 charges to a peak value at a slow rate but discharges quickly thus its voltage represents the blade temperature. In order to measure the temperature of  individual blades a capacitor 84 is provided for each blade and is charged up from circuit 78 through a sequencing switch 82 which is operated by multi-vibrator 96 slaved to the rotation of the engine by trigger probe 98, 100. The radial length of the blade that can be inspected is altered by gate 80 which is operated by width trigger 118. The output devices 68, 126 may be meters or recorders or alternatively the output can be used in the control system of the engine.
Patent GB-316548-A (GB)
Title: Improved process for working up crude potash salts
IPC: C01D3/08
Filed: 1929-06-15
Abstract: 316,548. Chemieverfahren Ges. July 30, 1938, [Convention date]. Sodium bicarbonate; potassium sulphate.-In a process for working up crude salts containing potassium chloride, they are treated with an ammoniacal ammonium chloride liquor originating in the process. The potassium chloride, which remains undissolved, is separated, and the liquor is cooled and treated with carbon dioxide so as to obtain ammonium chloride and one or more metal carbonates. For example, if the crude salt is mainly sylvinite, i.e. chlorides of potassium and sodium, the potassium chloride remains undissolved and is separated, whilst the sodium chloride goes into solution and is then precipitated as sodium bicarbonate. Ammonia and crude salt are then added to the liquor and the process repeated. If carnallite, i.e. chlorides of potassium and magnesium, are treated with the liquor, the potassium chloride remains undissolved and is separated, and magnesium ammonium carbonate is then precipitated by carbon dioxide. Ammonium chloride is then precipitated by cooling, and the liquor is freed from carbon dioxide ready for re-use. Crude salts containing carnallite and kilserite, i.e. chlorides and sulphates of potassium and magnesium, and also crude salts containing anhydrite, i.e. calcium sulphate, rock salt and alumina can be treated in a similar way. If the crude salts contain bromine compounds, these become enriched in the lyes. To obtain them, the liquor is heated to expel ammonia and the ammonium chloride is decomposed with lime and the bromine obtained from the calcium chloride lye. Specification 311,226 is referred to.

Abstract: 460,518. Forced-flow steam boilers. TENNANT, W. J. (La Mont Corporation) June 28, 1935, No. 18558. [Class 123 (ii)] In a forced-flow boiler comprising a number of generating tubes supplied with water in the manner described in Specification 294,619, [Class 123 (ii)], water from a collector 38 is forced by a pump 12 into a header 8 and through contracted orifices into tubes 2 extending along the inner walls of the combustion chamber and along the walls of an annular flue 22 surrounding the chamber and terminating in an annular header 32 arranged outside the chamber. A pipe 36 conducts steam and water from the header 32 to a separator 158 in the upper part of the collector, and the dried steam is taken through a pipe 42 to a coiled tube superheater 44 in the annular flue 22. The concave rear wall 62 is protected by steam generating tubes 66 arranged in spiral coils. Water is supplied to these coils from a header 68 and they discharge into the annular steam header 32. The hot gases from the annular flue 22 are directed through a second annular flue 78 containing tubes 84 through which flows the air for combustion in the burner. Air entering through apertures 98 in the front wall passes along a jacket 94 surrounding the boiler and after flowing in a sinuous course through a rear jacket 106 is directed into the tubes 84, from which it flows into the burner through apertures 7 in the burner casing. The burner is protected from excessive heat by a coiled steamgenerating tube 154 supplied with water from the header 8 and discharging through a tube 156 into the pipe 36. A conical baffle in the separator 158 has projections 162 directing the steam and water in a spiral course. Water passes through apertures 166 in the baffle, and the steam flows upwards to a further separator consisting of a spiral pipe 172, from which separated water flows into the lower part of the collector through a pipe 178.

Title: Improvements in extinguishing fire
IPC: A62D1/00
Filed: 1928-06-27
Abstract: 319,083. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 27, 1928. Chemicals.-A process of extinguishing fires, particularly of finely divided combustibles, consists in spraying on to the combustibles a dilute aqueous solution of a highly active wetting agent not in the form of a foam. Such wetting agents referred to include soaps or saponin, the sulphonation products of organic compounds, such as Turkey red oil or the mixtures produted by the sulphonation of mineral oils or tars or fractions thereof. One example consists of one to two parts of the sodium salt, of a nahthalene sulphonic acid, containing one or more propyl or butyl groups, in one hundred parts of water. For extinguishing fires in closed compartments, wet steam loaded with a wetted agent may be used. In a modification of the process, combustible matter is sprayed with the wetting agent so that, in case of fire, water which is then sprayed on will quickly penetrate the matter. Specification 289,630 is referred to.
